Theoretically I can't see why it would not work, the pump would be on any time that the relay fwd or rev were set to 0 (Depending on which you wired it to) Strangely I can't find it in the rules where it states which devices can be tied to the GND Blocks.
Here is what it says:
Except as noted herein, each Ground (GND) wire from a speed controller, relay, or Robot
Controller must go directly from that item to one of the 12 Common (-) terminal tabs on the
circuit breaker/ fuse blocks.
Exception: The Ground (GND) wires from low current items such as solenoid control and
rotating light relays, custom circuit, optical sensors, LEDs, and fans may be connected as a
group to one common wire leading back to a Common (-) terminal tab.
But it doesn't specifically seem to say the output side of the spike or speed control to the motor, however the exception is for low current items only. Either way the RED is no longer available so it doesn't matter much.
